Answer:

10 m/s²

Explanation:

Given data

  • Initial velocity (u): 0.0 m/s
  • Final velocity (v): 30.0 m/s
  • Displacement (s): 45.0 m
  • Acceleration (a): ?

We can detemine the acceleration of the car using the following kinematic expression.

v² = u² + 2 × a × s

2 × a × s = v² - u²

a = v² - u² / 2 × s

a = (30.0 m/s)² - (0.0 m/s)² / 2 × 45.0 m

a = 10 m/s²
